My invention relates to radiators, and 'par- -tieularly to panelradiators.

In heating rooms, a 'better distributionof heat is obtained Whereconvection currents are relied upon for distribution'of heat from aradiator to the lremote parts'o-f the room thanis obtained Whereradiation, alone, is relied upon. The temperature o'flthe lradiator mustbe maintained considerably aboye @the I 'temperatureof theremote Apartsof the room, Where radiation is relied upon inorder'to see'ure thedesired average temperature. 1n suoli cases, the radiator is often toohot to permit persons to Iremain near it.

Radiators heretofore-used have genera'lly presented-an unsightlyappearance dueto the Vpresence o-f a large number of thin ends ofyradiator columns and intervening spaees which are usually in shadow:and servea's dust 29 vaccumulatore.

I provide 4a radiator unit `having a substan- #tial-ly Vcontinuouslyexposed surface `of 4considerable area. This exposed surface may-be oornamental -to harmonize with 'the furniture 2 and Walls of a room. Thelrear surface is provided with a series of grooves constituting'passageways or stacks for t1 ne lmovement of I convection currentsbehind the radiator limit.

l This surface usually faces awafll of the room. A 'l-"he ends of theradiator units ta'persli'ghtly Afrom the exposed face, and formcontinuous lcorners with the exposed surface from lthe 'top tothe bottomof the radiator fso that aA 'plu- -rality of radiator sections maybeplaced 'end Y to 'end forconstituting yanasse'mbled radiator. Thesubject matter of this easeis related #to that of my copendingapplication,I'Serial Number 308,274, led September 1&5-, 1928, which hasnonT matured `into Patent No.

Referring to the drawings, aradiatorQ `com-prises `a plurality A-ofradiator sections 4 placed in iend-'to-end relation. The radiatorsections are conneotec'l'byvpipe nipples v5 'eX- 'tending `intoAopenings 6 disposed aft lthe to'p and Abottom of `each radiatorsection, such manner fof connection being AWell `known in the art..

Each 'radiator section 4comprises a central 'portion 7.the "outersurface 'of which is oon- 'situtedfby a continuousy'walfl Stliat nriesin :substantially a single plane. The surface ofthe WallS is provided'with `small grooves 9 'and rai-sed ].iortions "10 to "correspond tothejoints formed between adjacent sections and presenta pan eled'a ppeara'n ce. ylith th'is'eonstruction, a number of radiator sections may -befastened "together Vin end-'to-end relation andthe `entire `outer`surface of the radiator present substantially the appearance "thatwould be given were Va plurality of 'short 'see- .tions used, Whoseldges i'termin'a't'ed at .the *groovesY 9. p

The i'nner'surfaees of `vthe bodyportion '7 between the portions 1l lare vprovided 'with l ay pluralityVYof outwai diy 'extending 'ribs 15. The ribs ldefine grooves Aor`passages 16 lthrough "which A ai'r currents inove'by Convection Thefi'rregl'ilar contour deli-ned bythe ribs 15 increases 'the rer "surfaceofA the radiator fse'c'ti'on'and -a fsu-res t fthe'air in moving over itYYabsorbs "ftheinr orpor-t'ion of ftheheat 'by convection rather than byradiation. T he "heating fof the 'room by radiationinrlie forward volvesa thermal gradient throughout the room, from the radiator to the mostremote part of the room. A more nearly uniform heating of the room isobtained where the air is passed frequently over the surface of theradiator by convection currents. If it is desired to maintain the sametemperature in a room, it is not necessary to maintain the radiator atas high a temperature where convection currents are relied upon as whereradiation is relied upon.

Clamping bolts 18 extend longitudinally of the radiator by which theradiator sections 4 are held together. As shown in Fig. 5, brackets 19extend into the spaces 19a formed between opposing walls of two abuttingsections and engage the hubs for the nipples. The brackets 19 areprovided with notches 2O for clearing the clamping bolts 1S and aresecured toan adjacent wall or other support. Where brackets are used tosupport the radiator, the latter is particularly adapted for mounting ina recess 21 -in a wall 22.

While I have shown the use of two brackets in this figure, it is to beunderstood that the lower bracket may be omitted if desired. A space isleft beneath the radiator and air currents move upwardly between thewall 22 and the flanges 15 and inner surfaces of the wings 11 of theradiator. The air moves across the top of the radiator and escapesbeneath an overhanging portion 23 of the wall. The radiator may be usedalone or with various types of enclosures and space filling fittingshaving provision for the passage of air cnrrents through the radiator,of which there are many on the market. An example of such a constructionis shown in my copending application.

Referring to Figure 4L, the radiator may also be mounted on legs 24resting on a floor 25.

Each radiator section is adapted to be used as a complete radiator. Byassembling the radiator sections in endtoend relation and connectingthem, a radiator of any suitable length is provided.

While I have shown and described certain preferred embodiments of myinvention, it is understood that the invent-ion may be otherwiseemployed within the scope of the following claims.

I claim:

1. A radiator section comprising a hollow L 'fa e ex enc ino` in bodyportion having a suii c t l g substantially a single plane, the oppositesur face of the body portion being provided with ribs defining aplurality of grooves, and hollow end portions of greater width than thebody portion and ribs, said end portions having continuous wallsextending at substantially right angles to the continuous surface of thebody portion and having openings for the reception of pipe connections.

2. A radiator section comprising a continu- 'body having hollow wings ateach end thereof and a hollow panel portion between the wings, the space1n the wings and the space in the panel being continuous to permit theflow of 'fluid therethrough, the front surface of the body extendingsubstantially in a single plane, the rear face of the panel portionbetween the wings having heat dissipating projections thereon.

4. A radiator section comprising a hollow body having hollow wingportions at each end thereof and hollow panel portion between the wingsand connecting the wings, the interior of the body providing acontinuous fluid circulating space, the front surface of the bodyextending substantially in a single plane, the rear face of the panelportion of the body between the wings being corrugated, said wingshaving nipple receiving openings in the end faces thereof which aredisposed rearwardly of the panel portion of the body.

5. A radiator section comprising a body portion having front and rearwalls spaced from each other, the exposed surface of the front wallextending in substantially a single plane, the rear surface of the bodyportion being provided 1Vith ribs defining a plurality of grooves, andhollow end portions of greater width than the body portion, the space inthe end portions communicating with the space between the front and rearwalls of the body.

6. A radiator section comprising a body portion having spaced front andrear walls, the exposed surface of the front wall extending insubstantially a sinfrle plane, the exposed surface ofthe rear wall ofthe body portion being provided with ribs defining a plurality ofgrooves, and hollow end portions of greater width than the body portionand ribs, the space in the end portions communicating with the spacebetween the walls of the body, said end portions having walls extendingat substantially right angles to the continuous surface of the bodyportion.

In testimony whereof I have hereunto set my hand.
